It has never been more important to look professional. That means having a clean bright white smile. If you want a whiter smile but prefer gel toothpaste, check out Colgate MaxWhite Toothpaste. It has Mini-Bright strips full of polishing silica to remove stains, and an icy mint flavour to freshen breath. It may not be fair, but yellow teeth and dandruff broadcast messages about more than grooming. Like tell-tale tobacco odor, some employers may interpret yellowish teeth as a sign of sloppiness and a lack of education.
